Just tested in a fully up-to-date Kubuntu 20.04 VM (amd64), and I cannot observe the problem. Printing an e-mail does pop up the print dialog in front of the thunderbird window.
Can you share the exact steps you're taking to reproduce the problem? Can you maybe attach a screencast demonstrating it?
